problem signing in to ssh

I generated public /private keys for passwordless entry to server using the following link..
Now when i try to log in ssh still asks for my password and even I give correct pwd it still does not allow me.
I get following error message
Invalid user <user> from <myIpAddress>
input_userauth_request: invalid user <user>
pam_unix(sshd:auth): check pass; user unknown
pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=<myIpAddress>
pam_succeed_if(sshd:auth): error retrieving information about user <user>
Failed password for invalid user <user> from <myIpAddress> port 53326 ssh2
but if i log in and disconnect with root a few times and try logging in with my own id , after a few attempts ssh allows my id to login. its such a strange behaviour. heres the generated log when i succeed
Accepted publickey for <user> from <myIpAddress> port 57482 ssh2
pam_unix(sshd:session): session opened for user <user> by (uid=0)
please help me out as it is too irritating and sometimes takes more than half hour to log in

Hello and Welcome to LinuxQuestions,

Have you set the permissions correctly to your authorized_keys file on the server side? I've had strange behavior when they were off sometimes.

Another thing worth indicating is that SSH will not accept your 'invalid user' after a few attempts, if the user doesn't exist then it doesn't exist and SSH will not let you in. Check the username you type in when trying to access the SSH server.

Kind regards,
